First claim
Opening claim text (preview).
What is claimed is: 1. A valve regulated lead-acid battery comprising a positive electrode plate, a retainer mat and a negative electrode plate, which are housed in a container and holding an electrolyte solution respectively, and the electrolyte solution containing colloidal silica, wherein the electrolyte solution contains lithium ions, a silica content in the electrolyte solution is 1% by mass or more and 5% by mass or less, and a lithium-ion content in the electrolyte solution is 0.02 mol/L or more. 2. The valve regulated lead-acid battery according to claim 1 , wherein the lithium-ion content in the electrolyte solution is 0.02 mol/L or more and 0.4 mol/L or less. 3. The valve regulated lead-acid battery according to claim 1 , wherein the electrolyte solution is not gelated. 4. The valve regulated lead-acid battery according to claim 1 , wherein the negative electrode plate comprises a negative electrode grid comprising a Pb—Ca—Sn-based alloy. 5. The valve regulated lead-acid battery according to claim 1 , wherein the colloidal silica has an average particle size of 10 to 20 nm. 6. The valve regulated lead-acid battery according to claim 1 , wherein the retainer mat comprises glass fibers or synthesized fibers. 7. The valve regulated lead-acid battery according to claim 1 , wherein the lithium-ion content in the electrolyte solution is 0.02 mol/L or more and 0.5 mol/L or less.
